= Sigma-additive set function
{wiki=Sigma-additive_set_function}
A sigma-additive set function, often referred to in the context of measure theory, is a type of function defined on a σ-algebra (sigma-algebra) of subsets of a given set. This function satisfies a specific property related to countable additivity, which is a fundamental concept in measure theory. **Definition:** Let \\( \\mu \\) be a set function defined on a σ-algebra \\( \\mathcal\{F\} \\) of subsets of a set \\( X \\).
